93 XL 2WD - Serious Brake issues

[geffy]

Driving over to a band job yesterday afternoon I get smoke coming out from under the driver's side wheel, with notable drag in acceleration. Then the brake pedal goes to the floor There's stopping power, but not a great deal.
My only warning this migt happen was the ABS light going on earlierin the day; I shut off the car and turned it back oin again, and it stayed off.

Anyway, I somehow get the car to the gig, played the night, then called AAA to have it towed home. It's at the shop now and with the holiday weekend I'm not gonna have it looked at before Tuesday. Gives me time to wonder...Assuming the master cylinder is shot, or the left front caliper was seizing up, what might I expect to hear from the mechanic? (DIY is not an option at this point.)

This Ex is very low mileage for its age (58K now) and was very well maintained, but I expect most of the parts they encounter are gonna for something like this are gonna be original.

Scary thing: Two weeks ago the family and I took this car to a wedding in Connecticut - 650 miles round trip. It could have happened at a much worse time, like waiting to get on the GW bridge. I'm really thinking I dodged a bullet here.

Anyway, any contributions to help a newbie eliminate some anxiety would be most welcome....

Just a guess but it's coming from experience. The front left (driver's side) caliper slide pin probably caused the caliper to stick and the pad to get eaten up due to lack of lubrication. The heat build-up from the brake pad rubbing probably caused the grease in the wheel bearing to start cooking. You may end up with having to replace that caliper and possibly the rotor. If the rotor is salvageable, you will need to have it turned. Rebuilt calipers are not expensive nor are they difficult to replace. If the pad was worn down to nothing, the pad can come loose from the caliper and get caught between the caliper piston and the rotor and possibly break the piston. The factory caliper piston is made of a hard, brittle plastic called bakelite. Rebuilt or refurbished brake calipers for the 1st Gen ex's are available with either bakelite pistons or steel pistons. It would be a good idea to replace both front calipers, (new slide pins are usually included) get a new set of pads and new rubber brake hoses and then completely flush the old brake fluid out when you go to bleed the brake system. Check the wheel bearings very carefully for bluing which indicates they severely overheated. If they have overheated, get new bearings and races. The old races will need to be pressed out of the rotor and the new ones pressed in. Proper and regular maintenance of the caliper slide pin and guides are essential to proper operation and longevity.
